I suggest the one at NAS Jax is great, but inaccessible unless you have a CAC, military credentials and a Florida driving licence. There are about a dozen aeroplanes on display, but I’d say the hassle of getting on base isn’t worth the visit.
IMHO, by far and away, the museum at NAS Pensacola is the best in Florida. It’s a fair way from ORL though. If you’re lucky, you’ll catch the Blues flying; they are superb.
